Background Seasonal Affective Disorder is a recurrent depressive disorder which usually begins in the fall/winter and enters into remission in the spring/summer, although in some cases may occur in the summer with remission in the autumn-winter. In this study the authors evaluated the association between seasonal changes in mood and behavior with psychiatric disturbance. Method Descriptive, cross-sectional study. Participants, students attending higher education and vocational courses (N = 324), were evaluated with the Seasonal Pattern Assessment Questionnaire (SPAQ) and the Screening Scale for Mental Health (ER80). Results Among the respondents, 12.7% showed seasonal affective disorder (SAD), 29.0% showed subsyndromal seasonal affective disorder (s-SAD) and 58.3% did not show significant seasonal affective symptomatology. As for psychiatric morbidity, 36.6% of subjects with SAD and 13.8% of those with s-SAD were considered “psychiatric cases” whereas for subjects without SAD this value was only 3.2%. Conclusions There is a statistically significant association between psychiatric morbidity and seasonal affective disorder. This association corroborates the importance of the Seasonal Pattern Assessment Questionnaire in screening for seasonal fluctuations in mood and behavior related disorders, and the clinical need for recognition of these conditions, particularly associated suffering and disabilities.

Vehicular Ad Hoc Network (VANETs) are self-configuring networks where the nodes are vehicles equipped with wireless communication technologies. In such networks, limitation of signal coverage and fast topology changes impose difficulties to the proper functioning of the routing protocols. Most applications critically rely on routing protocols. Thus in this work, we propose a methodology for investigating the performance of well established protocols for MANETs in the VANET arena. Three routing protocols are considered: AODV, DSDV and OLSR. To ensure a meaningful evaluation of the protocols, we devised a realistic simulation environment in terms of network characteristics, communications protocols and traffic patterns. We consider the VanetMobiSim software for a more realistic simulation of vehicular movements in urban environments, as well as the NS-3 package for traffic and communication emulation. Simulation results have led to conclude that the routing protocols analyzed present variable performances in the VANET scenario, with OLSR outperforming the other studied protocols.

This paper combines conceptual tools from discourse and social theories to analyze a particular speech that former Brazilian president Luiz Inacio Lula da Silva delivered at the end of his second term (2007)(2008)(2009)(2010) in the Complexo do Alemão, a neighborhood located in one of the poorest areas of Rio de Janeiro. It attempts to highlight how Lula breaks with a longstanding tradition of Brazilian politicians who have chiefly represented the political elites. While using a specific rhetoric, Lula constructs (and is constituted by) a "populist" locus of enunciation. Drawing from Ernesto Laclau's theory of populism, this paper argues that populist logic in Latin America should not be understood pejoratively, but rather as a particular way of doing politics. It thus claims that Lula positioned himself and his interlocutors as "the people," a specific Revista de Estudos da Linguagem, Belo Horizonte, v.25, n.2, p. 681-710, 2017 682 discourse that breaks with certain Eurocentric expectations about the "appropriate" language of politics in Brazil. Keywords: Discourse; text; context; Lula; Complexo do Alemão; populism.Resumo: Este artigo articula conceitos oriundos tanto da teoria linguística quanto social de forma a analisar um discurso proferido pelo expresidente do Brasil, Luiz Inácio Lula da Silva, no fim do seu segundo mandato (2007)(2008)(2009)(2010) no Complexo do Alemão, um bairro localizado em uma das regiões mais pobres do Rio de Janeiro. O artigo aborda o modo como Lula rompe com uma tradição de políticos brasileiros que representam primariamente as elites. Por meio de uma retórica específica, Lula constitui (e é constituído por) um lugar de enunciação "populista". Engajado com a teoria do populismo de Ernesto Laclau, este artigo propõe que o populismo na América Latina seja entendido não de modo pejorativo, mas como um modo próprio de realizar política. Assim, argumenta-se aqui que Lula posicionou a si e a seus interlocutores como "o povo", um discurso específico que rompe com certas expectativas eurocêntricas do que seja a linguagem "apropriada" da política no Brasil.

Introduction: The Attention Deficit Hyperactivity Disorder (ADHD) has been regarded for years as a disorder of childhood and adolescence only, without being properly studied and deepened its implications in adulthood. Objective: To determine the implications of cognitive, emotional and social aspects of ADHD throughout the life cycle and reflect on the continuity of the diagnosis and treatment of childhood and adulthood. Methodology: Review based on scientific papers published in the last 10 years using "Attention Deficit Hyperactivity Disorder" and "adult" as keywords (MeSH). Results: Epidemiological studies have shown that 50-80% of children who have ADHD remain the same difficulties in adulthood. The underdiagnosis of ADHD in adults is due to the mitigate of hyperactivity and impulsivity with the age. However, inattention continues to affect the adult presenting these difficulties academically or at work, as low frustration tolerance, sleep disturbances and higher levels of anxiety and depression than the general population. Other studies found that 20-40% of adults with ADHD have a history of substance abuse, especially illicit drugs and tobacco. Conclusion: The ADHD causes significant and inadequate behavioral changes throughout life. Therefore, it is essential to a proper recognition and treatment of adults with ADHD as a good articulation between Child and Adolescent Psychiatry and Adult Psychiatry, in order to improve the prognosis and quality of life.
